PhD position on sample-efficient quantum gate calibration at FZ Jülich
The Peter Grünberg Institute for Quantum Control (PGI-8) at the
Forschungszentrum Jülich, Germany, is offering a fully-funded PhD
position for three years to pursue unique research on sample-efficient
gate calibration methods based on quantum optimal control. The
successful candidate will be jointly supervised by Prof. Dr. Felix
Motzoi (PGI-8) and Dr. Markus Heinrich (University of Cologne).
Among other applications, optimal control theory has proven its
utility for the optimal calibration of quantum gates early on and has
since been used routinely in experiments. The calibration is typically
based on a figure of merit derived from experimental data, such as the
average gate fidelity provided by the randomized benchmarking protocol.
In realistic scenarios, these quantities however require a significant
measurement effort to be estimated, especially in the high-precision
regime relevant for fault-tolerant quantum computing.
You will investigate recent advances in characterization and
benchmarking protocols for their suitability to provide efficient cost
functions for the optimal control of gate calibration in full-stack
quantum computers and simulators. Based on your assessment, you will
develop new, sample-efficient optimal control approaches for gate
calibration and test them in numerical simulations. You will pursue your
research with the German research collaboration QSolid,
https://www.q-solid.de , coordinated by Forschungszentrum Jülich. You
will work with experts in quantum optimal control at Forschungszentrum
Jülich (Prof. Dr. Felix Motzoi, Dr. Francisco Cardenas-Lopez), and in
quantum characterization at the University of Cologne (Dr. Markus
Heinrich). We aim at implementing your results in in-house experiments
at Forschungszentrum Jülich. You may consult the works by Felix
Motzoi and
Markus
Heinrich for an impression of the relevant research.

About PGI-8:
The Peter Grünberg Institute for Quantum Control (PGI-8) at the
Forschungszentrum Jülich specializes in novel optimization strategies
for emerging quantum technologies. These emerging technologies aim to
provide transformative changes to our society, including how we think
about information, and unlocking vast calculations for the natural
sciences, logistical problem solving, and high-performance computation.
Our group has pioneered the application of quantum optimal control
methods to quantum computation and many-body quantum systems. This
includes the development of physical models and model reduction
techniques as well as algorithmic advances of in-situ optimization and
machine learning to tackle the complex processes inherent to scalable
quantum devices.
